Class
    Foam::zeroInletOutletFvPatchField

Description
    This boundary condition provides a generic outflow condition

    Zero gradient is applied for outflow and a zero value applied for reverse
    flow.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            zeroInletOutlet;
    }
    \endverbatim
